Configuration files in .NET applications serve different purposes based on application type. Web.config is used exclusively for ASP.NET web applications, managing web-specific settings like authentication, session management, database connections, and URL routing through IIS. App.config is designed for desktop applications (Windows Forms, Console, WPF, Windows Services), handling application-level settings, API endpoints, and logging configurations. When compiled, App.config is renamed to match the executable name. Both files enable developers to customize application behavior without modifying source code, but they target distinct deployment environments.
